Madrid have mountain to scale against Dortmund

Real Madrid CF welcome Borussia Dortmund to the Santiago Bernabéu for the semi-final second leg with it all to do after Robert Lewandowski's four goals in Germany gave Jürgen Klopp's team a 4-1 lead to take to Spain.

• Despite Cristiano Ronaldo's 50th UEFA Champions League goal in Dortmund, Madrid need a big improvement against visitors who have already come close to winning in the Spanish capital this season. When Klopp's men visited the Merengues in Group D in November, they led 2-1 until Mesut Özil's 89th-minute free-kick equaliser.

• While Dortmund are eyeing a second European Cup final, Madrid are aiming for their 13th. They have suffered three semi-final defeats since last lifting the trophy in 2002 but have got the better of Dortmund at this stage before.

• To repeat their 1998 success against the Bundesliga side, Madrid must match the record for the biggest first-leg victory overturned in the competition's UEFA Champions League era. AC Milan lost 4-0 at RC Deportivo La Coruña in the 2003/04 quarter-finals having won 4-1 at home.

Past meetings• Madrid ended Dortmund's reign as European champions in the 1997/98 semi-finals. Fernando Morientes and Christian Karembeu's first-leg goals in the Spanish capital earned a 2-0 aggregate triumph for Jupp Heynckes' charges, who went on to collect the trophy. Current Dortmund sporting director Michael Zorc and youth team coordinator Lars Ricken featured in both games for Nevio Scala's side.

• Madrid also overcame Dortmund 2-1 at home in the 2002/03 second group stage as Raúl González and Ronaldo overturned Jan Koller's goal. Six days later Koller struck again but Javier Portillo's added-time effort made it 1-1. Madrid qualified in second place, one point above Dortmund.

• Sebastian Kehl and then reserve keeper Roman Weidenfeller are still at Dortmund and Iker Casillas at Madrid.

• In this season's group stage, Lewandowski and Marcel Schmelzer scored either side of Ronaldo's strike to give Dortmund a 2-1 home victory over Madrid on 24 October. In Spain 13 days later, Dortmund led twice through Marco Reus and Álvaro Arbeloa's own goal, with Madrid replying through Pepe and Özil. Those four points against the Merengues ensured that Dortmund finished as Group D winners.

Match background• Dortmund are unbeaten on their travels in this season's competition, with one victory and four draws, but Madrid have won three and drawn two at the Santiago Bernabéu this term. They have won 14 – nine by a margin that would keep them in the competition this time round – and lost just one of 17 European home outings during José Mourinho's three campaigns in charge.

• Madrid's record against German visitors is W18 D4 L2. Last season they beat FC Bayern München 2-1 in the home second leg of their UEFA Champions League semi-final but lost the penalty shoot-out that followed. Bayern, with victories in 2000 and 2001, are the only Bundesliga team to have won at the Bernabéu.

• Dortmund drew 0-0 at Málaga CF in the quarter-final first leg. Their overall record in Spain is W1 D4 L5. That sole success was a 1-0 triumph at Club Atlético de Madrid in the UEFA Champions League group stage in 1996/97 – the campaign they won the trophy.

• Madrid's record in two-legged ties with German clubs in UEFA competition is W11 L7; Dortmund's record against Spanish sides reads W4 L2.

• This is the third UEFA Champions League semi-final appearance for Dortmund, who have reached one final:1997/98 Real Madrid CF, lost 0-2 (0-2 a, 0-0 h)1996/97 Manchester United FC, won 2-0 (1-0 h, 1-0 a)

• While this is Klopp's first UEFA Champions League semi-final, for Mourinho it is the seventh: his record is W2 L4. His Inter outfit won the 2010 final against Bayern, though Madrid did lose to the same opponents in last season's last four. On the two occasions Mourinho's sides did make the final, they claimed the trophy.

• Dortmund have surrendered a three-goal first-leg lead before – the only time in 14 UEFA ties they lost the tie after winning the first game at home. Club Brugge KV turned round a 3-0 reverse in Germany with a 5-0 home success in the 1987/88 UEFA Cup third round.

Team ties• Nuri Şahin made ten appearances for Madrid in 2011/12 after signing from Dortmund. He returned to BVB on a season-and-a-half loan in January, having spent the first half of this campaign farmed out to Liverpool FC.

• Germany's Schmelzer, Mats Hummels, Mario Götze, İlkay Gündoğan, Sven Bender, Kevin Grosskreutz and Reus are international colleagues of Madrid duo Sami Khedira and Özil. All bar Bender and Grosskreutz figured in Germany's 3-1 friendly loss to Argentina in August. Khedira (own goal) and Ángel Di María were on the scoresheet and Gonzalo Higuaín also played. Higuaín also got the only goal in Argentina's 1-0 March 2010 win against Germany in Munich.

• Hummels played in Germany's 1-0 UEFA EURO 2012 group stage victory over a Portugal team featuring Pepe, Fábio Coentrão and Ronaldo.

• Neven Subotić was in the Serbia team beaten 2-0 by Luka Modrić's Croatia in March. He and Serbia also lost 2-0 to a Spain side including Casillas, Sergio Ramos, Xabi Alonso and Raúl Albiol last May.

• Özil played for Dortmund's local rivals FC Schalke 04 between 2006 and January 2008 before joining SV Werder Bremen. His only goal against Dortmund in seven games came for Bremen in a 1-1 home draw in November 2009.
